What is ferromagnetic memories ?

AI Thread Summary
Ferromagnetic memories, often referred to as core memory, utilize ferromagnetic rings through which wires are threaded to store binary data. By passing current in different directions, the magnetic polarity of the rings can be altered, representing binary values of 0 and 1. This setup allows for the storage and computation of information, as the ferromagnetic material can retain its magnetic state for a period, preserving the stored data. The technology is significant for its ability to maintain data integrity without continuous power, making it a foundational concept in the development of memory storage systems.

What is ferromagetic memories ?

I need matter on this help me please, searching so many webs can't get proper matter :(
 
Computer science news on Phys.org
Try googling 'core memory'
 
In short it is like this , you have a wire going through an ferromagnetic ring, you can have two poles , pass the current in one way and you have N S pass it the other way and you have S N ,So for a given input you have either one or the other output , now insert the binary code in all of this and you get either 0 or 1.
have many of these wires going through many rings and you have many ones and zeros and now you can compute some information. + you can store it because the ferromagnetic piece if not distracted will stay at it's last state for a while (keeping it's magnetic polarity) atleast some materials tend to do this.

Thread 'Urgent: Physically repair - or bypass - power button on Asus laptop'

Asus Vivobook S14 flip. The power button is wrecked. Unable to turn it on AT ALL. We can get into how and why it got wrecked later, but suffice to say a kitchen knife was involved: These buttons do want to NOT come off, not like other lappies, where they can snap in and out. And they sure don't go back on. So, in the absence of a longer-term solution that might involve a replacement, is there any way I can activate the power button, like with a paperclip or wire or something? It looks...
